Over the years I've experienced this both good and bad situation. After playing with a random player, let's call them x, if you both queue up after the game, there is a high chance that you both are going to be in the same game again. It's cool to play with the same players sometimes. I've become friends with some of them as well, thanks to that! But there are also times when I report a player and am "forced" (that's not the word I'm looking for, and this is the first and only word that come to my mind) to play with them again right afterwards. It doesn't bother me that much, I just mute them and try to have fun, but I hink it may be frustrating for some players, maybe for me as well. So maybe Riot can make it so that after reporting a player that "system" won't work?
Don't get me wrong, I'm not really complaining about it, because it's not always bad. I just wanted to hear your opinion!
